1.1 General Introduction

Section 2 – Safety Considerations and Precautions

Before installing and operating the H-Type® High Temp Precleaner with V-Tips, it is important to review and understand

the following safety information.

There are set-up, maintenance and operational activities involving both stationary and operating conveyors. Each case

has a safety protocol.

2.1 Stationary Conveyors

The following activities are performed on stationary conveyors:

• Installation • Blade replacement • Repairs

• Tension adjustments • Cleaning

DANGER

WARNING

It is imperative that OSHA/MSHA Lockout/Tagout

(LOTO) regulations, 9 CFR 1910.147, be followed before

undertaking the preceding activities. Failure to use LOTO

exposes workers to uncontrolled behavior of the belt

cleaner caused by movement of the conveyor belt. Severe

injury or death can result.

Before working:

• Lockout/Tagout the conveyor power source

• Disengage any takeups

• Clear the conveyor belt or clamp securely in place

Use Personal Protective Equipment (PPE):

• Safety eyewear

• Hardhats

• Safety footwear

Close quarters, springs and heavy components create a

worksite that compromises a worker’s eyes, feet and skull.

PPE must be worn to control the foreseeable hazards

associated with conveyor belt cleaners. Serious injuries

can be avoided.

2.2 Operating Conveyors

There are two routine tasks that must be performed while the conveyor is running:

• Inspection of the cleaning performance

• Dynamic troubleshooting

Every belt cleaner is an in-running nip hazard. Never

touch or prod an operating cleaner. Cleaner hazards

cause instantaneous amputation and entrapment.

Never adjust anything on an operating cleaner.

Unforseeable belt projections and tears can catch on

cleaners and cause violent movements of the cleaner

structure. Flailing hardware can cause serious injury

ordeath.

Belt cleaners can become projectile hazards. Stay as far

from the cleaner as practical and use safety eyewear and

headgear. Missiles can inflict serious injury.

Section 3 – Pre-installation Checks and Options

• Check that the cleaner size is correct for the beltline width

• Check the belt cleaner carton and make sure all the parts are included

• Review the “Tools Needed” list on the top of the installation instructions

• Check the conveyor site:

- Will the cleaner be installed on a chute

- Is the install on an open head pulley requiring mounting structure

- Are there obstructions that may require cleaner location adjustments

3.1 Checklist

In certain applications it is necessary to modify the location of the precleaner pole due to permanent obstacles that obstruct

the desired location. Relocating the pole location can be done easily and does not hinder the performance of the cleaner as

long as the “C” dimension is maintained.

NOTE: In the following example we will be lowering the pole location in the “Y” direction, but the same method

could also be applied in the “X” direction.

Conveyor situation:

Pulley Diameter: 24"

X = 7-3/4"

Y = 12"

C = 14-1/4"

1. Determine the given location dimensions and define the change needed. After laying out the given X & Y dimensions,

determine the distance of the modification required for adequate clearance of the pole and tensioning system. (In the

example we decide to lower the pole 2" to clear the support structure).

2. Write down known dimensions. We can now determine two of the three required dimensions which will allow us to find

the third. We know we cannot alter the “C” dimension, so this will remain the same. Also we are required to lower the unit

in the “Y” dimension 2", so we add 2" to the given “Y” dimension.

X = ?"

Y = 12 + 2 = 14"

C = 14-1/4"

3. Determine final dimension. On a flat vertical surface, using a level, draw one horizontal line and one vertical line creating

a right triangle (Fig 3a). Measure down from the intersection the determined “Y” dimension and mark (Fig 3b). With the

tape measure starting at the modified “Y” mark, swing the tape across the “X” line and mark at the “C” dimension where it

crosses the “X” line (Fig 3c). Measure from the intersection to the “C” intersection and this will be your new “X” dimension

(Fig. 3d).

X = 2-5/8"

Y = 14"

C = 14-1/4"

Section 4 – Installation Instructions

Before You Begin:

• Installation specs and instructions are based on the assumption

that the conveyor is in its working position (angle). If the

conveyor angle will be different, the cleaner should be installed

per the final position. Call the BCP Help Line 1-800-253-8132 if

you need help with determining the proper coordinates.

• Choose instructions for chute mounting or open head

mounting. For chute mounting it may be necessary to cut

an access hole to allow for installation and inspections.

(See dimensions in Step 7 under Chute Mounting.)

• Follow all safety precautions when using a cutting torch.

• If welding, protect all fastener threads from weld spatter.

6.2 Test Run the Conveyor

• Run the conveyor for at least 15 minutes and inspect the cleaning performance.

• Check the tensioner spring for recommended length (proper tensioning).

• Make adjustments as necessary.

6.1 Pre-Op Checklist

Section 6 – Pre-Operation Checklist and Testing

NOTE: Observing the cleaner when it is running and performing properly will help to detect problems or when

adjustments are needed later.

Section 7 – Maintenance

Flexco belt cleaners are designed to operate with minimum maintenance. However, to maintain superior performance

some service is required. When the cleaner is installed a regular maintenance program should be set up. This program

will ensure that the cleaner operates at optimal efficiency and problems can be identified and fixed before the cleaner

stops working.

All safety procedures for inspection of equipment (stationary or operating) must be observed. The H-Type® Precleaner

operates at the discharge end of the conveyor and is in direct contact with the moving belt. Only visual observations can

be made while the belt is running. Service tasks can be done only with the conveyor stopped and by observing the correct

lockout/tagout procedures.

7.1 New Installation Inspection

After the new cleaner has run for a few days a visual inspection should be made to ensure the cleaner is performing

properly. Make adjustments as needed.

7.2 Routine Visual Inspection (every 2-4 weeks)

A visual inspection of the cleaner and belt can determine:

• If the spring length is the correct length for optimal tensioning.

• If the belt looks clean or if there are areas that are dirty.

• If the blade is worn out and needs to be replaced.

• If there is damage to the blade or other cleaner components.

• If fugitive material is built up on the cleaner or in the transfer area.

• If there is cover damage to the belt.

• If there is vibration or bouncing of the cleaner on the belt.

• If a snub pulley is used, a check should be made for material buildup on the pulley.

If any of the above conditions exist, a determination should be made on when the conveyor can be stopped for

cleaner maintenance.

7.3 Routine Physical Inspection (every 6-8 weeks)

When the conveyor is not in operation and properly locked and tagged out a physical inspection of the cleaner to

perform the following tasks:

• Clean material buildup off the cleaner blade and pole.

• Closely inspect the blade for wear and any damage. Replace if needed.

• Check both blade pins for proper installation and condition. Replace if needed.

• Ensure full blade to belt contact.

• Inspect the cleaner pole for damage.

• Inspect all fasteners for tightness and wear. Tighten or replace as needed.

• Replace any worn or damaged components.

• Check the tension of the cleaner blade to the belt. Adjust the tension if necessary.

• When maintenance tasks are completed, test run the conveyor to ensure the cleaner is performing properly

7.4 Blade Replacement Instructions

Section 7 – Maintenance

Tools Needed

• Tape measure

• (2) 1½" wrenches or crescent wrenches

• (1) 17mm wrench

• Wire brush (for cleaning pole)

• Small putty knife (for cleaning pole)

1. Remove the tension. Loosen the adjusting nuts on the mounting

bracket/J-bolt assembly to remove tension from the arm (Fig. 1). This

releases the tension of the blade on the belt.

2. Remove the worn tips. Remove the nuts on each tip and remove the

tips from the cushion (Fig. 2). Clean all fugitive material from the pole.

NOTE: If tips are hard to remove use a screwdriver or hammer to

loosen it and then remove.

Physically lock out and tag the conveyor at the power source

before you begin cleaner installation.
